Specication of Letters Patent.

Patented July 2, 1907.

Application filed May 16, 1904. Renewed November 14, 1908. Serial No. 343,438.

To all whom lit may concern:

Be it known that I, CHARLES BRENT, residing at Rat Portage, Province of Ontario, Dominion of Canada, a subject of the King of Great Britain, have invented certain new and useful Improvements in Feed-Regulators for Steam-Boilers, of which the following is a specification, reference being had therein to the ac.- companying drawings.

The invention relates to new and useful improvements in feed regulators for steam boilers, and consists of a balanced receptacle arranged on the plane of the Water level in the boiler connected to a valve which.

controls Athe supply of water to the boiler, said receptacle being rocked by the changing level oi'water in the boiler, and thereby correspondingly actuating a valve t0 open and close the same as the water level rises or falls.

The invention .further consists in the combination with this particular construction of water regulator, of an automatic low water alarm. And the invention further consists in the peculiar construction, arrangement and combination of the various parts more fully hereinafter described and particularly pointed out in the claims. l

. In the drawings Figure I is a vertical section through a steam boiler showing my invention applied thereto,

the receptacle being shown also in section and the other partsvof the apparatus in elevation, and showing in full in dotted lines the different positions of the parts. Fig. 2 is a horizontal section through the valve and the journals for the counterbalance receptacle, the receptacle and frame being shown in plan. Fig. 3 is a ver tical section on line x-- Fig. 2, and Fig. 4 is a detached sectional view illustrating the construction of the low water alarm contacts on line y-y Fig. 3.

At A I have shown a diagrammatic section through the steam boiler, which may be of any suitable construction.

B is a steam pump; C the steam supply pipe therefor; and D the water outlet pipe leading to the water space of the boiler.

In this case I have shown my automatic regulator applied to the steam pipe C, the valve therein opening and closing the steam supply to the pump closing the steam supply to the pump as the valve, to be hereinafter described, is opened or closed. It is obvious withoutillustration or description that the valve could be applied to the water supply pipe D if it were properly shaped and located, or to the exhaust pipe of the pump, and still'operate to control the supply of water to the beller in the same manner. I do not deem it necessary to illustrate these various and other connections, for they are obvious to anyone ,familiar with steam and i Water supply for boilers.

In the steam supply pipe C I have shown the valve casingE, being what is called a straightway valve, and

having the rocking segment F for opening and closing the connection from the valve casing to the steam end of the pump. This segment F has on its outer surface the slotted lug a in which is engaged a squared portion b of the valve stem c. This valve stem extends through an ordinary stuliing boxd at one end. At the other end of the valve casing I provide any suitable support for the rocking "frame, and in this case I have shown it as a pin pr studie, in axial line with the valve stem.

G is`a frame journaled on the line of the axis of the valve stem. In this case I have shown the frame provided with the bearing h secured to the valve stem, and the bearing t' journaled on the stud e. The frame is provided with the adjustable counterweight H at the other side ofthe pivot or fulcrum with a receptacle I. l In this case I have shown the receptacle connected to the frame by the steam and water pipes .l and J the steam pipe leading to the top of the receptacle and the water pipe to the bottom thereof. -These two pipes .I and J lead into the frame and connect to passages K and K in the axis of rotation of the frame, which passages have connected to them the short nipples L and L., each having a suitable flange I'.2 at their outer ends.

M and M/ are coupling and packing nuts by which the two nipples L and L are connected to the stationary steam and water pipes N and Nl respectively, these two pipes connecting to the steam andl water supply of the boiler, as shown in Fig. l. The couplings M and M permit of a rocking movement 0i the frame in relation to the stationary pipes N and N and such rocking movement will move the segmental valve F to open 0r close the steam connection from the steam supply space of the boiler to the pump in the specific construction herein shown.

The receptacle I is located with its central horizontal axis in the plane at which the water is desired to be maintained in the boiler, and when the Water is at the desired level the receptacle will be half filled with water, for instance, and will be balanced by the counterbalance weight H inthat position, as shown in full lines in Fig.l l. In case the water in the boiler lowers, the water will correspondingly lower in the receptacle when the counterbalance weight will descend, lifting the receptacle and opening thesteam supply to the pump, which will then operate to force water into the boiler until the desired level has again been reached, which will also cause the increase of water in the receptacle to bring it back to its middle position and close the steam valve, thus stopping the operation of the pump. In this way, at all times, the water level in the boiler will be accurately maintained and without the use of fioats, or any device apt t0 give trouble, inside of the boiler space. Inasmuch as it is desirable to have an alarm sounded when very low water is present in the boiler, I prefer to connect to my device an alarm which will be operated on the occasion of extremely 10W water. This may be (lone by placing the Contact block O on the frame G l and placing below that block the two terminals k and l of an electric circuit; so that when the block O is lowered suliciently to contact these terminals which are supported on the bracket P, the circuit will be closed and the bell will be rung. Of course, the block O and the terminals l and lc are suitably insulated from the metallic supports.

What I claim as my invention is:-

1. The combination of :1 pipe, a valve therein which will control the supply of water to a boiler, the valve stem, a coiinterlmlanced frame joui-nailed on the axis of) the valve siem, a receptacle on the frame, constant pipe connections from the iop and bottom of the receptacle to the steam and water space of the boiler, said pipe connections leadinf.: one through each end of the axis of the frame, and a swivel lioint in said connections permitting the rocking of the frame in relation to the stationary pipe connections.

L. 'lhe combination of a pipe, a valve therein which will control the supply of water to a boiler, 21 valve stem, a counterbalanced frame journaled on the axis of the valve stein, a receptacle on the frame, constant pipe connections from the top and bottom of the receptacle to the steam and water spaces ol the boiler, said pipe connections leadin."r one through each end of the axis of the frame, a swivel joint in said connections permitting the rocking of sesso? 3. 'lhc combination of a valve adapted to control thev supply of water io the bolei'vand located on the plane of thc normal water level of the boiler, of a rocking.: al'ln jonrnaled on the axis of the valve stem, connections from Vsaid rocking',r arm to the valve stein, a receptacle on the frame` constant connections from the receptacle to the steam and water supply of the boiler one through each end oi' the axis of rotation ot the frame, substantially :1S

described. l

4. 'lhecpmbination of a valve adapted to control the supply of water to the boiler. a stem for the valvc. a frame journaled on the axis of the valve stein and conA nected to said stem, a i'rnlne (l havim,r the counlcr balanced weight II, a receptacle l, the pipes .l and .l' connected to passages in the frame located in thc axis of rotation thereof, the nipples l. and L', and thc stationary steam and water connections N and N and swivel connections between said pipes and the nipples L and L'.

ln testimony whereof l aiiix my signature in* presence of two witnesses.
